Sbutter by moving Lever D at the side up as
           far as possible. As the shutter is of the
          safety pattern, the leaves always renrain
          closed when setting.

Ctn,
Speed     of the Premo Shutter may be varied from
          one-tenth to one-fiftieth of a second, de-
         pending on the position of the Speed Wheel
       C at the side. As the wheel is revolved

downward the speed of the shutter is accel-  .
          erated, and by reversing the motion, the
         tension is reduced, thus decreasing the
        speed. The letters F and S on the wheel
           indicate whether shutter is set for a fast or
        slow movement. For ordinary work the
          slowest will be found sufficiently rapid;
        but for views containing swiftly moving
           objects, set shutter at the highest speed.

                 FOR TIME EXPOSURES
              the Camera should be placed on a tripod
              or other suitable support, as you will be
               unable to hold it steady enough to avoid a
       -         blur. /           To set the shutter for time exposure,
    -              simply move the Release Button up as f.ar$
               as possible, antl adjust the Lever D the same

            as for Instantaneous work. Open the Shutter
        by pushing Release Button, and after re-
         moving the plate holder frorn canlera, drop
          the panel in the back. Through the aper-
           ture you can see the reflected image (always
           reversed) on the ground-glass. Adjust the
           front by nreans of the hook until the view
          desired is perfectly clear, then clamp it in
           place by turning Focusing Hook to one sicle.
         Place proper diaphragm in  position by
           rotating clisc. Close the shutter by a gentle
           pressure on Release Button. Slide the plate
          holder between screen and rigld frame of
          Camera, the screen exerting sufficient pres-
          sure to keep the holder in place. Now set
        the shutter by moving lever D upward,
        draw the slide of holder nearest the Lens
        and all is ready for the exposure.
